Thanks, checked that screen and all was clear. Pulled off exhaust manifold found little blockage , cleaned that and tested the sensors on that side and all seem fine. Searching to find if there is a thermostat that may be blocked but it seems there is NONE on a VX Deluxe?? Is that correct? Looking to find the engine temp. sensor think it is under intake but can not find it, will have to try and trace wires and see how hard it is to access and test that. Running on flush the alarm does go off after 5 minutes of running. Any ideas on where to look next is appreciated.
